Scale Factors/Geometric Figures
The base of a triangle is 2 cm and the height is 2.5 cm.
The scale factor is 1cm = 2 ft.
What is the actual base length of the scale drawing?
2cm x 2ft = 4 feet
Angle 6 and 7 are supplementary angles. If Angle 6 is 28 degrees, what is the measurement of Angle 7?
152!
28 + ? = 180
180 - 28 = 152
What is the circumference of a circle with a diameter of 24 cm?

a ratio!
Angle 1 and Angle 2 are complementary angles. If Angle 1 is 42 degrees and Angle 2 is (3x), what is the value of x?
16!
42 + 3x = 90
3x = 48
x = 16

Angle ABC and Angle DBE are vertical angles. ABC is 40 degrees and Angle DBE is (x/6). What is the value of x?
240!
40 = x/6
40 x 6 = 240
The area of a circle is 153.86 square meters. What is the diameter of the circle? Use 3.14 for Pi
14!
153.86/ 3.14 = 49
Square root of 49 is 7 (the radius)
Radius x 2 = Diameter
Diameter = 14
Surface area of a house with dimensions of 8ft by 8ft by 8ft with a triangle height of 4ft!
5 Squares (walls + bottom)
4 Triangles (roof)
384ft squared!
------------------------------------------
SA of Bottom = 8 x 8 = 64 (1 square)
64 x 5 (5 squares) = 320ft
SA of Triangle = 8 x 4/ 2 = 16 (1 triangle)
16 x 4 (4 triangles) = 64 ft
320 + 64 = 384ft squared!
